摘要
在分析岩溶陷落柱的导水机理及其影响因素的基础上,根据陷落柱的岩体结构力学和水文地质特征,提出了陷落柱的三种导水类型。结合皖北矿区巷揭陷落柱的特点,建立两类不同的导水陷落柱地质模型,并运用FEM软件对其导突水风险进行了定量预测。
Base on the analysis on the water conducted mechanism and the influence factors of the karst sink hole and according to the rock structural mechanics and hydrogeological features, the paper provided three type water conducted sink holes. According to the features of the sink holes exposed in the mine roadways of the north part of Anhui Province, there were two different types of geological modes for the water conducted sink holes set up, The water inrush risks were quantitatively predicted with FEM software.
